Description
The Power Switch product family is specially designed for
an off-line SMPS with minimal external components. The
Power Switch consist of high voltage power SenseFET and
current mode PWM IC. Included PWM controller features
integrated fixed oscillator, under voltage lock out, leading edge
blanking, optimized gate turn-on/turn-off driver, thermal shut
down protection, over voltage protection, and temperature
compensated precision current sources for loop
compensation and fault protection circuitry-compared to
discrete MOSFET and controller or R
CC
switching converter
solution. The Power Switch can reduce total component count,
design size, weight and at the same time increase efficiency,
productivity, and system reliability. It has a basic platform
well suited for cost-effective design in either a flyback
converter or a forward converter.
